On the bus half deflection forward stick is taken prior to setting the T/O thrust (full deflection for >20 kt X-wind or and tail wind). This is to keep the N/W firmly on the ground for steering during the time the pitch power couple would try to lift the nose. At 80 knots the NHP calls and checks the HP releases, slowly, the forward pressure. This tells the NHP the HP is 'alive' and gets rid of the nose wheel loading as, above 80kts, the aerodynamic effects of the rudder outweigh the effects of the nose wheel steering.
